SHUTTER-FASTENER.

Specification of Letters Patent.

Application filed November 4, 1904. Serial No. 231.373.

T 11]] It'll 07M it may concern.-

Be it known that I, EMIL NIGGLI, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented new and useful Improvements in Shutter-Fasteners, of which the following is a specification.

My invention relates to a shutter 01' blind fastener, and has for its object to provide simple and reliable means for fastening or looking the sh utters or blinds so that they cannot be opened from the outside.

The invention consists in a spring-catch or other similar device which extends from the under side of the meeting-rail of the upper windoi *-sash and engages a keeper on the shutter. Means are also provided for locking the catch, which means extend through the meeting-rail from the upper side thereof. By this construction a fastener is had which cannot be worked from the outside, and which is therefore safe and reliable.

In the accompanying drawings, Figure 1 is a vertical section of a portion of a window and the shutters or blinds, showing the fastener applied thereto. Fig. 2 is a section on the line 2 20f Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 2.

Referring specifically to the drawings, 5 denotes the meeting-rail of the upper windowsash, and 6 that of the lower sash. The shutters or blinds are indicated at 7. A casing 8 is secured to the under side of the rail 5, which casing contains a sliding block 9. A catch 10 extends from the block through an opening 11 in the casing and engages a keeper 12 on' the shutter. The side of the casing next to the rail 5 is closed by a plate 13, having a projecting stud 1 1, which extends into a slot formed in the block 9. The plate 13 is fastened by a screw 16, extending from the outer side of the easing into the stud 14:. A spring 17 is placed in the slot 15, which spring bears against the stud 14 and the wall of the slot opposite thereto, whereby the block is pushed rearwardly and the catch is held normally in locking position.

The rear end of the block 9 has a hole 18 to receive a locking-pin 19. This pin extends through the meeting-rail from the upper side thereof, the rail being recessed, as at 20, to receive the pin. The recess is closed on top by a plate 21, which has a slot 22, through which the pin is extended. The plate 13 has on its upper side a stud 24, which extends into the recess 20. A hole is made in the stud and plate, which registers with the hole 18 when the catch is in locking position. The outer end of the pin is bent to form a loop 25, and its free end is extended into the recess 20 and is formed with a terminal barb or hook 26, which catches under the plate 21 and prevents withdrawal of the pin. The pin can be removed from the recess, if desired, by pressing the barbed end inwardly sufliciently for the barb to clear the plate 21. The pin is made of stout spring-wire, so that the barbed end thereof binds it in the slot 22. This holds the pin in elevated position and prevents it from dropping back into the hole 18 when it is pulled out of the same to unlock the catch.

At 27 is indicated a handle for releasing the catch from the keeper after it is unlocked. This handle extends from the block 9 at right angles to the catch through an opening 28 in the under side of the casing. Said handle carries a plate 29, which extends over and closes the opening 28.

For convenience in handling the shutters a ring 30, as shown, is provided.

In use it is necessary only to remove the pin 19. This frees the block and permits the catch 10 to engage the keeper 12 when the shutters are closed. The pin is then inserted into the hole 18, which looks the block 9 in the casing and prevents the catch from being withdrawn from the keeper. To open the shutters, the pin is withdrawn, whereby the block is freed, after which the handle 27 is taken hold of and the catch removed from the keeper, after which the shutters are free to be opened. The locking-pins cannot be operated unless the lower sash is down, after which the said sash has to be raised to reach the handle 27. As the pin cannot be reached from the outside, the fastener is safe and reliable and cannot be tampered with.

Various changes in the construction and arrangement of the parts described herein can be made without departing from the spirit and scope of the invention, and I do not wish to limit myself to the precise construction shown except as indicated in the following claims. The catch can be made either right or left.

Having thus described my invention, what is claimed as new, and desired to be seen red by Letters Patent, is

l. The combination with a shutter and the meeting-rail of the upper sash of a window, of a sliding block on the under side of the rail, a catch extending from the block, a

IIO

keeper on the shutter for the catch, and means extending through the rail from the upper side thereof for locking the block against movement.

2. The combination With a shutter and the meeting-rail of the upper sash of a Window, of a casing secured to the under side of the rail, a block slidable in the casing, a catch extending from the block, a keeper on the shutter for the catch, and a pin extending through the rail from the upper side thereof into the block'for locking it against movement.

3. The combination With a shutter and the meeting-rail of the upper sash of a Window,

of a casing secured to the under side of the rail and open on one side,'a plate over said opening and having a stud extending into the casing, a block slidable in the casing and having a slot to receive the stud, a spring in the slot between the stud and the Wall of the slot sonso 5. The combination With a shutter and a window-sash, of a sliding block carried by the sash, and having a catch extending therefrom, a keeper on the shutter for the catch, and means for locking the block.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
